However, it looks like two of the major browsers including Firefox and Google Chrome are already working on supporting the SPDY/3 protocol. While the SPDY/3 protocol is restricted to Sandbox builds of Firefox. Google Chrome dev and canary build versions also support SPDY/3 through a switch in about:flags. The support for SPDY/3 is available on Windows, Linux, Mac OS X and Google Chrome OS.

The SPDY protocol is definitely a step towards the future of the web and with major browser support it could help speed up how we access content on the web. Right now, other major browser like Internet Explorer, Safari and Opera do not support SPDY, but hopefully they should do it in newer versions of their browser.
